【摘要】 选取Ohta和Suito的经验公式和光学碱度模型计算不同组成成分的四元渣系(Al2O3-CaO-MgO-SiO2)的硫容量与平衡状态下的硫分配比,分析渣中各组元成分变化和钢水温度变化对硫分配比的影响。通过计算首都钢铁集团公司某炼钢厂LF精炼渣的硫容量与硫分配比,来验证计算模型,优化精炼渣成分,以期获得最佳的脱硫效果。更多还原

【Abstract】 The sulphur content of the Al2O3-CaO-MgO-SiO2 series of various constituents in the slag and the sulphur distribution ratio under the equilibrium condition are calculated and the effects of change of various constituents in the slag and variation of the hot metal temperature on the sulphur distribution ratio analyzed using the empirical expression derived by Ohta and Suito and the Young et al.’s model.By calculation of the sulphur content in the LF refining slag and the sulphur distribution ratio in a specific Steel-making Plant of Shougang the calculation model is validated and the compositions of the refining slag optimized in a bid to achieve the best desulphurization effect.更多还原
